Pferd 44698252 POLINOX PNST Cross Buff, 25 mm, 2 Layers, Aluminium Oxide, Grit 100
Available
These Pferd POLINOX PNST cross buffs are listed in 25 mm and 38 mm diameters, each in grit 100 and grit 280. The catalogue says they are made in aluminium oxide (A) (manufacturer-stated).
The catalogue describes the PNST type as suitable for cleaning, deburring and fine grinding of inner surfaces and contours, and particularly suitable for hard-to-reach places such as drilled holes and indentations (manufacturer-stated).
It says the cross buffs are highly flexible, which allows them to adjust to the contour, with cool grinding and low thermal load on the workpiece, and that the open structure and flexibility of the non-woven material prevents the tool clogging (manufacturer-stated).
The 25 mm buff has 2 layers (optimum 10,000 rpm, maximum 19,100 rpm) and the 38 mm buff has 3 layers (optimum 7,500 rpm, maximum 12,600 rpm). The catalogue says to order a compatible arbor separately (manufacturer-stated).

Selecting the right option
A higher grit number is a finer abrasive, so grit 280 gives a finer finish than grit 100. Choose the diameter to suit the hole or contour. Never exceed the maximum speed listed for the item (manufacturer-stated). Wear eye protection, hearing protection, gloves and a dust mask, and follow the safety instructions (manufacturer-stated).
